Calculating probability that a business will find a buyer and sell

Bare with me whilst I try and explain this one. I work for a business that finds companies to buy a client business that's signed up with us. I have been compiling a spreadsheet with data of deals completed and closed during the past 2 years, and what I want to do is find a way to calculate the probability that a business will be able to be sold based on parameters such as profit%, turnover, sector, and other fields like that. Is there any way of doing this? I have about 169 deals that I can refer to, hopefully this is a significant amount of data to do this.
